Cocked&Locked said:When I bought my 9 xd, they accidently shipped it with 40 mags, are your mags 40 or could they be 9? Both will work, but not as well as they should, and 9 in 40 mags puts you over capacity. Look at the base plates and make sure they say 40.
beltfed said:Keep in mind this will not be a dead give away, as the base plates are interchangable. (mags coming from the factory with the wrong base plates probably would not be a common problem, but you never know...) Comparing a known-to-be 9mm body and feed lips will be 100%
